WILLIAM E. JOHNSON, OF ST. JOSEPH, IV'IISSOURI. Y

VULCANIZER.

T0 aZZ whom ii -may concern:

Be'it known that I, WVILLIA EJJOHNSON,

residingat St. Joseph,fin the county of.

Buchanan and State of"Missouri,'have invented new and usefulImprovements in Vuloanizers, of Which the following is a specifi cation.I r This invention relates to portable vulcan- 1 izers, and comprehendsa construction by means of which the shoe ofapneumatic tire can bequicklyand easily'repaired without mum combustion space as well as alarge amount of heating surface, the wings or partitions radiatingheatto the vulcanizing face of the'device whichis brought'into directcontact with the shoe or. case.

The nature and advantagesof the in vention will bejbetter understoodwhen the "following detail description is read in connection with theaccompanying drawings, the'invention' residing in the combination,construction and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals ofreference indicate the similar parts in the several views and wherein VFigure 1 is a side elevation of a tire showing the manner of using theinvention. 7

Fig. 2 is a sectional view taken on line 22 of Fig. 1.

Fig. 3 is a perspective view of the vulcanizer.

Fig. 4is a detail view of the hood removed.

Fig. 5 is a section on Fig. 4.

The device forming the subject matter of my invention comprises a casingor the like 10 which is substantially of rectangular configuration, anddivided by a vertically disposed partition 11 into what I term acombustion chamber 12 and a cool air chamber 13. The casing is open atits top, while the front wall of the casing is provided with a pluralityof draft openings 14 arranged with relation to the bottom of the casingto define the fuel capacity of the casing, and in this manner only theproper amountv of fuel can be arranged within the container toefiiciently vulcanize the shoe 15 to which the de- Specification ofLetters Patent.

vice is applied. The rear wall of the case 16 constitutes thevulcanizing face which is brought into contact with the shoe or case,and islslightly curved to conform to the shape of the shoe asillustrated. Arranged within the combustion chamber 12 is a pair ofdiamertically arranged. wings or partitions 17 which intersect at apoint adjacent the partitionll, while forming an integral part of thesewings or partitions is a partition 18 arranged centrally of the casing10 and also intersecting the partitions 17 at their point ofintersection. The partition 18 is substantially T-shaped the head ofwhich is indicated at'19. These partitions provide for a' maximumheating surface and radiate heat from the combustion chamber 12 to thecoolair chamber 13. The construction as well as the relative arrangementof the various wings or partitions is not only efiicient for thispurpose, but also affords the container a largecombustion space. Thepartitions contact the partition 11 which forms one wall of the cool airchamber, while the partitions terminate in spaced relation to thebottomof the container-t0 provide a fuel chamber the fueljbeing indicated at20, The cool airchamber is also divided by partitions 21 which serve toradiate the heat from the artition 11 to the vulcanizing face 16 of tfiecontainer. A hood of the configuration illustrated in arranged upon thevulcanizer to prevent the heat from coming in contact with the adjacentparts of the tire being repaired or other parts of the vehicle whichwould be detrimental to such parts. This hood includes opposed sidewalls 22 which are connected by a top wall having an upwardly inclinedportion 23 which is arranged above the corn bustion chamber 12, and ahorizontally disposed portion 24 which covers the cool air chamber 13.Projecting inwardly from the end. walls 22 are pins or the like 25 whichrepose upon the upper edge of the casing 10 to support the hood isproper position thereon. In addition to protectingthe parts of thevehicle from the detrimental efiect of the heat, it is quite obviousthat the hood 23 prevents the escape of heatfrom the device, therebyrendering the vulcanizer highly efficient for the purpose intended.Projecting from the opposed sides of the container 10 are slotted lugs26 through which are adapted to be passed threaded bolts 27 and havingassociated therewith thumb nuts 28.
